Anterior segment analysis using OCT3

Optical coherence tomography has been used for many years, in particular in the field of the retinal imaging, and is a promising technique in the analysis of the anterior segment, providing a similar resolution to histology for ocular tissue. We present a collection of images obtained with the OCT3 (Carl Zeiss Meditec, Dublin, CA), with parameters set to obtain good-quality images of the iris and corneal structures. The OCT provides detailed analysis of the cornea, precise assessment of the dimensions and locations of corneal lesions - in the anterior-posterior plane as well as transversally or obliquely - with 10-microm precision, and the study of the iridocorneal angle and its dynamics. Using the highly precise OCT3 for retinal imaging, it is possible to obtain good-quality anterior segment imaging, which makes the device highly versatile and thus increases reasons for acquiring this type of apparatus. OCT3 users should not neglect this potential of the device, already in wide use for examining the retina.
